Quizplus · Accepted Answer

Color blindness is linked to a recessive gene on the X chromosome. Females have two X chromosomes, so they would need two copies of the gene to be color blind. Males only have one X chromosome, so if their X chromosome carries the gene for color blindness, they will be affected.
